How is magnesium measured?
The molecular weight of magnesium is 24.3 g/mol, with a 2+ valence (Mg2+). The normal serum magnesium level is 0.7 to 0.85 mmol/L, but it is often expressed as equivalents per liter, 1.4 to 1.7 mEq/L (mEq/L = mmol/L × valence), or in conventional units, 1.7 to 2.1 mg/dL (mg/dL = mmol/L × molecular weight divided by 10). Normal reference levels vary from laboratory to laboratory.
